Namuhla, i-GL ikhuluma ngezinyathelo ezijwayelekile zokuthi ungathuthukisa kanjani ukuqina kwe-thermalIzintambo ze-OPGW:
1. Indlela yomugqa we-shunt
Intengo yeIntambo yokubona ye-OPGWiphezulu kakhulu, futhi akukhona ukonga ukwandisa kuphela isigaba esiphambanayo ukuze sithwale i-short-circuit current.Ivamise ukusetshenziselwa ukusetha ulayini wokuvikela umbani ohambisana nentambo yokubona ye-OPGW ukuze kuncishiswe amandla amanje ekhebuli yokubona ye-OPGW.
Ukukhethwa komugqa we-shunt kufanele kuhlangabezane:
a.Yiba ne-impedance ephansi ngokwanele yokwenza i-OPGW yamanje yehle ibe ngaphansi kwevelu evumelekile;
b.Ingakwazi ukudlulisa umthamo wamanje omkhulu ngokwanele;
c.Kufanele kube nesici sokuphepha samandla esanele ngenkathi ihlangabezana nezidingo ezahlukahlukene zokuvikela umbani.
Kufanele futhi kuqashelwe ukuthi nakuba ukumelana komugqa we-shunt kungancishiswa kakhulu, ukusabela kwayo kwe-inductive kwehla kancane, ngakho-ke umsebenzi womugqa we-shunt unomkhawulo othile;Ukukhethwa kwengxenye, kodwa ekushintsheni komugqa we-shunt oshintsha isigaba semodeli, uma umehluko phakathi kwezigaba ezimbili mkhulu, okwamanje kuzosatshalaliswa kukhebula le-OPGW, okuzokwenza ukuthi ikhebula le-OPGW likhule ngokuzumayo.Ngakho-ke, lapho ukhetha ingxenye yesiphambano somugqa we-shunt, ukubala kufanele kuphindwe.
2. Ukusetshenziswa kwezintambo ezimbili ze-OPGW
Olayini abade, ngenxa yokuthi i-short-circuit current yesigaba sokuphuma kwesiteshi esikhulu kunazo zonke, kufanele kusetshenziswe ikhebula le-optical le-OPGW lesigaba esiphambanayo esikhulu;emigqeni ekude nesiteshi esincane, kufanele kusetshenziswe ikhebula le-OPGW elincane eliphambanayo.Izinhlobo ezimbili zemigqa ye-shunt kufanele zicatshangelwe lapho kukhethwa izinhlobo ezimbili zezintambo ze-OPGW.
3. Indlela yokuguqula engaphansi komhlaba
Xhuma idivayisi yaphansi yombhoshongo wetheminali negridi yaphansi yesiteshi esinezinsimbi eziningana eziyindilinga ezineziphambano ezifanele, ukuze ingxenye yamanje yesiyingi esifushane ingene esiteshini esingaphansi komhlaba, okunganciphisa ngokuphawulekayo ukumanje kokuvinjwa komugqa ongenayo. Intambo yokubona ye-OPGW.
4. Indlela ehambisanayo yokuvikela umbani wezifunda eziningi
Xhuma imishini yaphansi yemibhoshongo yetheminali eminingana, ukuze umbane wesiyingi esifushane ugeleze ungene esiteshini esigudle imigqa yokuvikela imibani yezifunda eziningi, ukuze umsinga womjikelezo owodwa unciphe kakhulu.Uma ukuzinza okushisayo kwekhebula le-optical lesibili le-OPGW akuthembeki, idivayisi yokumisa phansi yombhoshongo wesisekelo sesibili ingaxhunywa, njalonjalo.Kodwa-ke, kufanele kuqashelwe ukuthi ukuvikelwa kokulandelana kwe-zero kufanele kucatshangelwe lapho kuxhunywa imibhoshongo eminingi.
